BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a system and method for remote activation of astorage operation of pictorial information, a wearable digital devicefor remote activation of storage of pictorial information and arecording device.

More specifically, the invention relates to personal wearable and sportsdevices, where the user wants to capture pictorial information in formof video footage of performances and situations, and store them forlater viewing, editing and sharing.

2. Description of Related Art

Various approaches to the problem of recording, editing, viewing andsharing of video information with personal devices are known. One suchapproach is presented in U.S. Pat. No. 8,613,937, where management ofbroadcasted and received video information with a mobile device isdiscussed. The content is not produced or edited by the user in any way,but filtering and bookkeeping features are offered for the content assuch.

Another approach is shown in U.S. Pat. No. 8,214,139, where a navigationdevice may be configured to trigger various actions based on GPSpositioning, an identified position change or acceleration. Suchrecording devices are however triggered by position data only, and thelength of the footage is determined by external conditions.

Another approach is shown in US Patent Application 2013/0343729, where asystem for semi-automated video editing is discussed. The system isbased on an algorithm for evaluation and classification of offered videocontent, giving as a result a compiled and edited version of the inputmaterial where selected sequences of the original video material isincluded based on action, facial expressions etc.

In sports and outdoor activities, it would often be desirable to collectmemories in the form of video footage during a performance or a mountaintrip, for example. There is no lack of cameras to take such footagewith, including the ones built-in into smartphone and PDA's. Editingsuch video material afterwards is time consuming and cumbersome. Alsoduring training, it would be important for the trainee and/or thetrainer to record certain sequences, perhaps taken a multitude of times,of the performance for later analysis. Long video sequences does notlend themselves easily to spot, isolate and view critical performancesteps, the duration of which may be only a fraction of a second.

Thus there is a need for a system which is able to take video clips onlywhen needed without a great deal of effort from the user and withouthaving to hold the camera in place. It is also a requirement to keep thenecessary editing at a minimum, whereby the video clips must be of alength and having a timeline around the triggering event that is knownin advance, rendering them easy to scan through in order to accept orreject.

SUMMARY OF THE INVENTION

It is thus an object of the present invention to present a solution tothe problems identified above, offering a solution based on two separatedevices with a wireless connection between them, and on sensorsconnected to one or both of the devices. The inventive system, methodand devices offer an efficient solution for collecting only relevantvideo footage around triggered events along an exercise or trip of anykind. The so collected video clips are easy to chain together to tell a“full” story, or to just browse through to select the most appropriateones for immediate sharing over a network or for editing.

With the aid of the present invention, the user need to spend less timeediting footage, capture the moments he or she wants to save. Theinventive concept also saves memory on memory cards typically used indigital cameras. Using pre-created or own-made applications for managingthe recording of footage, the user itself can define conditions forwhich the recording will take place.

It is an essential feature of the present invention that the recordingapparatus adapted to be in a mode of continuous capture of pictorialinformation. When the camera is set on, it will capture and keep acertain amount of video footage in memory where new footage erases theolder, as in an endless tape recording. Only when a command is issued toinitiate storage of the captured pictorial information, it will bepermanently stored in the memory of the camera. This facilitates storageof video material which was captured immediately before the storagecommand was issued, as well as after the command. The recording period,which obviously can be set by the user and heavily depends on the natureof the event, may use all time of the period to store the video signalup to the storage command was issued, the recording period may centeraround the storage command, the period may start with the storagecommand, or any combination thereof.

For the purposes of this description and in this context, the words“recording” and “capture” are used as synonyms describing the process ofrecording video footage at least temporarily in a recording device thatis set to be in a continuous recording mode. The word “store” and allits derivatives including “storage” are used for video footage or videoclips that is actually stored permanently for later viewing, editingand/or sharing.

The wireless communication system providing wireless link may be basedon radio technologies like Bluetooth or RFID, or any short-rangecommunication system.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1 is shown the main components of the inventive system: awristop computer 1, a unit 2 containing a video camera and ageneral-purpose computer 3 with a connection to an external network (notshown). If the camera unit 2 is a smartphone or tablet computer with enexternal (internet) network connection in itself, the computer 3 may notbe necessary. Also, not all the connections between the devices neednecessarily to be two-way communications. For example, in someembodiments of the invention, the wristop computer may only need to sendto the camera unit 2, but not to receive anything from it.

The general-purpose computer, or a service accessed with it from theinternet, may provide a programmable user interface for the wristopcomputer 1. Apart from obvious data selection and input needs, such asselecting display styles and colors of the display of the wristopcomputer 1, reading available measurement data from the wristop computer1 into the other computer 3, and downloading various user-selectedsoftware. An important task for the user interface being operable on thecomputer 3 (or the camera unit 2, if so equipped), is to allow forsetting or editing of parameters for the various applications running inthe wristop computer. These applications depend on the sensors availableto the wristop computer 1 and the needs of the user, and the parametersmay typically be sensor value trigger levels for activation of thecamera unit 2, video clip recording times, and so on.

It is clear that the two-way communication between the computer system 3and the wristop computer 1 may facilitate a user interface editor systeminstalled on the computer 3 that may be used for editing a userinterface of predefined applications running in the wristop computer 1.It is also within the scope of the present invention to store the dataand customized views in a format that is transferable as data files toother similar devices or social media, or to remote services e.g. on theinternet for bookkeeping and further processing.

In FIG. 2 is shown the wristop computer 1 and the camera unit 2 in moredetail. The wristop computer 1 has a processing unit 21 for runningcomputer programs and applications. A user interface unit 22 receivesmanual commands entered by the user e.g. by push-buttons 26. A memoryunit 23 is provided for storing operating systems, application programcode and received instructions. A sensor interface 24 provides a wiredconnection to one or more built-in sensors (not shown), and/or a wiredor wireless connection (see above) to external sensing devices.Typically, the sensors may be accelerometers, gyroscopes or otherorientation-detecting switches, timers, GPS-devices, shock sensors,inclinometers and so forth.

A wireless signaling unit 25 is needed for communication with the cameraunit 2 and/or any external computers 3 over a wireless link, as shown bythe arrow L. The wireless communication protocol used for communicationbetween computers, and/or between any remote sensors, may be a BluetoothLE or the proprietary ANT+ protocol. These are using direct-sequencespread spectrum (DSSS) modulation techniques and an adaptive isochronousnetwork configuration, respectively. Enabling descriptions of necessaryhardware for various implementations for wireless links are availablee.g. from the Texas Instrument®'s handbook “Wireless Connectivity” whichincludes IC circuits and related hardware configurations for protocolsworking in sub-1- and 2.4-GHz frequency bands, such as ANTI™,Bluetooth®, Bluetooth® low energy, RFID/NFC, PurePath™ Wireless audio,ZigBee®, IEEE 802.15.4, ZigBee RF4CE, 6LoWPAN, Wi-Fi®, GPS.

In FIG. 3 is shown a man on a snowboard with a wristop computer 30attached to his wrist and a camera 31 attached to his forehead by somesuitable fastening means. Obviously, the camera may be attached to anypart of the clothing, or to the snowboard. The wireless link L providesfor wireless communication between the two devices 30 and 31. If soprogrammed, the wristop computer will send instructions to the camera 31to start the storage of video clips when the ground speed, the verticalspeed or acceleration (on a steep slope) exceeds a certain limit, or thegravity (lack of vertical acceleration) is zero or below a certainlimit, indicating that the snowboarder makes a jump in the air. Thetrigger function may be based on any physical variable the sensors maydetect, and the trigger rules may be built by an editing function toconsider any combination of such variables, as will be explained laterin the examples. Editors for designing and editing triggers are as suchknown in the art. In this context, it is also possible and within thescope of the invention to provide the camera 31 with the desiredsensors, and to send in advance commands containing trigger informationby the wristop computer 30 to the camera 31. During the performance, thecamera 31 interprets the received sensing signals and try to match themwith the trigger information. When a match occurs, storage of pictorialinformation is initiated.

In FIG. 4 is shown the use of the present inventive system in a downhillski-related embodiment, where the camera 41 is stationary, and thewristop computer 40 attached to the wrist (or elsewhere) of a user isoperated to activate the camera 41 via the wireless link L to store aclip when the user approaches or passes across the line-of-sight of thecamera. In this way, repetitive footage can be taken e.g. for trainingand comparison purposes. It is clear that within the scope of theinvention, any number of cameras can be placed at a distance from eachother or at different angles with respect to a performance spot or alonga route. The triggering of the cameras may be manual or automatic, usinge.g. proximity sensing. The conditions at some spots of performance,like at a take-off ramp, easily create conditions that can make thesensors in the wristop computer 41 to trigger the camera to store theevent. Other performance spots to be monitored, e.g. on board of asailing ship, are more likely to be manually or proximity triggered.

FIG. 5 is a schematic and exemplary representation of video clips VC1 .. . VC6 stored in a semiconductor or magnetic memory. Thumbnail icons T1T6 showing the content of each of the video clips may be looked at forimmediate decision on how to deal with each of the clips. Of course, avariety of editing technologies exist and it is not in the scope of thepresent invention to deal with the art of managing video clips indetail.

FIG. 6 shows a flowchart diagram over the basic video clip storageprocedure according to the invention. In step 60, the wristop computer 1of FIG. 2 is monitoring the sensor signals. If the input signals at test61 exceed the pre-set trigger threshold for start storing video footage,a command to this effect is issued in 62 and communicated in step 63 tothe camera unit 2. The camera unit in this example, records the next 15seconds of video footage, and stores it with the previous 15 seconds ofcaptured video in one video clip, as those shown in FIG. 5. Obviouslyand equally well, the whole length of the clip could be stored fromvideo material captured before the command, and stop at the command.Vice versa, the whole length of the clip could be stored from videomaterial captured after the command and stopped after a predeterminedtime.

Examples 1. Ski Stunts

The user wants to record his friend's greatest jumps/stunts. After eachsuccessful jump, when button is pressed, 30 seconds of recorded videofootage preceding the pressing of the button is stored. User canpre-define the length of stored footage.

//if user is on moving and in free fall for longer that 2 seconds:record a movie clip 30 sec before and 30 after. if (SUUNTO_SPEED > 10 &&SUUNTO_G[2] < 1) { ACTIVATE.CAMERA_AFTERTHOUGHT(30); clipsrecorded =clipsrecorded+1; //show how many clips have been recorded RESULT =clipsrecorded; }

2. Using a Stationary and a Moving Device

Here, a user wants to get short clips without the need/possibility tomanipulate the camera on the go. Proximity determination can be based onsignal strength sensing, or it can be location-based using GPS. Forexample, the Bluetooth Low Energy (BLE) standard features proximitysensing. Other signal strength based options include ultrasound sensinge.g. in underwater applications or short-range inductive wireless(telemetric) devices. In location based proximity sensing, both thewristop computer and the camera may have GPS capabilities, or only thedevice on the move, provided that the position of the stationary deviceis fed into the GPS navigator.

Snowboarding with a helmet mounted camera, divers passing a stationarycamera, sailing boats passing a turning point buoy are examples ofuseful applications in this regard. Filming a skateboarding trick with acamera mounted in the rail is also feasible, e.g. by using the followingcode:

//If user is approaching the camera start filming. if(SUUNTO_PROXIMITY <15 && recording == 0){

ACTIVATE.CAMERA_RECORD( );  recording = 1; //when user is gone, stoprecording }else if (SUUNTO_PROXIMITY >15 && recording == 1){ACTIVATE.CAMERA_STOP( ); recording = 0; }

3. Mountain Biking

User wants to film the downhill trails (maintaining a high speed) of amountain bike expedition. He wants to automatically control the camerawhen hands can't be removed from the handlebar.

 if (SUUNTO_SPEED > 30 && recording == 0) { ACTIVATE.CAMERA_RECORD( );recording = 1; }else if (SUUNTO_SPEED < 20 && recording == 1){ACTIVATE.CAMERA_STOP( ); recording = 0; }

During such a trail, the user likely wants to record the best views,spots, jumps etc. Here the buttons of the wristop computer can be usedto bookmark the spots for future editing. The bookmarks can be saved tocamera memory as short clips, to allow faster editing.
